| Abstract: | In this paper,the structure and species of water absorbent resins used as lost-control materials(LCM) was reviewed.The effects of equilibrium swelling ratio were analyzed.Moreover,the methods for delayed expansion,such as coating,grafting hydrophobic monomer,using anhydrous liquid as the carrying fluid,etc,were summarized.Finally,the current problems and research suggestions of water absorbent polymers for LCM were proposed. |
